The correct answer is C. While the customs of Chanukah include eating latkes, giving monetary and other gifts and playing dreidel, the primary mitzvah of Chanukah is to light the menorah and display the lights, thus publicizing the miracle when the oil in the menorah in the Holy Temple burned for eight days instead of one.

In order to fulfill this mitzvah of publicizing the miracle, the menorah/chanukiah should be lit where it can be seen by the public. Chanukah lights were originally lit only in the doorway of the home, opposite the mezuzah, facing the street. However, it is now common practice outside of Israel to place the menorah in a window facing the street.

In order to make certain that the lights are visible, the menorah is lit after dusk. (There are two opinions regarding the correct time to light, so please consult your local rabbi.) On Friday evening, however, the menorah is lit before the Shabbat candles and extra oil (or longer candles) are used so that the Chanukah lights remain lit after nightfall.

If one is unable to light at the appropriate time, one may light later in the night, as long as there is someone else in the house who is awake (thus fulfilling the requirements of publicizing the miracle).

If it is very late and no one is awake, one should light the menorah without the blessings.

If there are still people in the street or in the apartments of a facing building who would see the lit menorah, it is permitted to light and say the blessings.

If the menorah was not lit at all during the night, there is no "make-up" lighting during the day.
